Title: Method for forming gold-plated pattern
Inventor: KUSHI KENJI
IPC: H05K3/24
Filed: 1990-06-06
Abstract: PURPOSE:To enable a good pattern to be formed under severe conditions by using a dry film resist composed essentially of a specified photosensitive composition and forming a photosensitive resin interlayer to further reinforce the gold plating resistance of the resist. CONSTITUTION:This photosensitive resin interlayer has an acid value of 10 - 100, and the dry film resist is composed essentially of a monomer having at least one ethylenically unsaturated group and a photopolymerization initiator and as a binder resin a thermoplastic copolymer of styrene or its derivative represented by formula I or its ring-substituted derivative, and a hydroxy-alkyl acrylate, a hydroxyalkyl methacylate, and a monomer having a 3 - 15 C alpha, beta-unsaturated carboxylic group. In formula I, R is H, halogen, or 1 - 6 C alkyl, thus permitting a good gold-plated pattern free from plating defects and the like to be effectively obtained.

Title: Pulse laser oscillator
Inventor: YASUOKA KOICHI
IPC: H01S3/097
Filed: 1990-06-06
Abstract: PURPOSE:To prevent the generation of arc discharge after glow discharge has disappeared by connecting a variable impedance device with a main electrode in parallel and further connecting this variable impedance device with a charging power source of a capacitor by way of a potential divider. CONSTITUTION:When a switch S1 is turned off, voltage is applied between a first main electrode 1 and a second main electrode 2 where glow voltage is generated. When the voltage between the first main electrode 1 and the second main electrode 2 approaches 0, the glow discharge disappears, but there remains in a capacitor C1. The residual voltage of the capacitor is controlled by an inductance Lv and a variable resistor Rv, which makes it possible to prevent the generation of oscillating voltage in a circuit so that the laser gas between the main electrodes 1 and 2 may return to a uniform density distribution swiftly. In addition, the resistance value of the variable resistor Rv can be most properly controlled by a potential divider Vd, responding to the voltage value of a high voltage power source Vc. It is, therefore, possible to prevent the generation of oscillating voltage definitely.

Title: Turbosupercharged engine
Inventor: NANUN SHINICHI
IPC: F02D15/00
Filed: 1979-11-12
Abstract: PURPOSE:To improve fuel efficiency and surely prevent knocking, by providing a means for setting a compression ratio and a means for timing the opening and closing of an intake valve. CONSTITUTION:An oil tappet 2 is in contact with a cam 3. A rocking cam 5 is mounted on a push rod 4. An intake valve 8 is in contact with a rocker arm 6. In a knocking region, the oil pressure of an oil pressure gallery 16 is heightened by a load detector 21 so that the volume of an oil pressure chamber 13 increases, the rocking cam 5 rotates clockwise and the cam 3 starts moving up. As a result, the valve 8 immediately starts acting. The effective compression ratio is thus lowered to prevent knocking.

Title: Controller for three-phase/three-phase pwm cyclo-converter
Inventor: KA GIYOUJU
IPC: H02P27/16
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent the oscillation of the input current of a cycle-converter by generating the carrier period turning on/off signals of bidirectional switches from input/output information and switching patterns and, at the same time, generating switch drive gate signals at a drive section. SOLUTION: A switch signal generating section 31 outputs the turning on/off signals of nine bidirectional switches 11-19 from a drive section 32, in accordance with switching patterns SP0h, SP1h, SP0m, and SP1m from a switching pattern generating section 26, the section numbers 1C1-1C3 of input current commands and section numbers 0C1-0C3 of output voltage commands from a first information updating section 29, and a reference signal Be from a second information updating section 30. Since the turning on/off signals are distributed to three output phases from only two switching patterns generated from only output interline voltage commands, the amount of on-line calculation of a CPU for control becomes smaller and a control circuit can be made simpler.  The information updating means control the input top phase and input set phase so that the phases do not change during the turned-on periods of the bidirectional switches between each output phase and an input 'Top' or 'Set' phase.

Filed: 1979-11-14
Abstract: PURPOSE: To improve the lifetime and reliability of the blade in high cooling efficiency and uniform distribution of temperature by a mechanism wherein an impingement cooling insert is made a double structure with internal and external inserts.  
     CONSTITUTION: The impingement cooling insert inside the blade is made a double structure and cooling air from a compressor is introduced into a plenum chamber  80.

Filed: 1983-08-10
Abstract: PURPOSE:To perform an exposure calculation to change automatically setting when a calculated value exceeds a set range, by providing a means which obtains data of an exposure range, which can be considered as a correct exposure, on a film vessel. CONSTITUTION:A set aperture value is stored in a register AVR3; and if the set value is between limit values AVO and AVM, it is stored as it is; but if it is not between them, limit values are stored over again. An exposure time TVAL is calculated on a basis of this set aperture value and an exposure value; and if this exposure time TVAL is shorter than the shortest exposure time TVM (TVAL>TVM), the difference is compared with exposure range data on the film vessel. When the difference exceeds range data, a correct aperture value AVAL where the shortest exposure time and range data are taken into consideration is calculated. If the exposure time is longer than the shortest exposure time, a similar processing is performed between the exposure time and the longest exposure time TVO.
